LOS ANGELES -- California Gov. Arnold Schwarzenegger says the state has adopted the world's first law to limit greenhouse gas emissions from fuel used by cars and trucks.

The law requires that producers, refiners and gasoline importers diminish the carbon intensity of their gasoline and diesel by 10 percent during the next 10 years. It also creates the groundwork for a planned mid-century goal in California of an 80 percent drop in all heat-trapping emissions.

The governor said the rule passed by the state Air Resources Board Thursday targets the gas emissions created from cars and trucks' fuel, making it a groundbreaking effort in the fight against global warming, the Los Angeles Times said.

The state regulation will "not only reduce global warming," Schwarzenegger said, "it will reward innovation, expand consumer choice and encourage the private investment we need to transform our energy infrastructure."

The Times said the regulation is expected to help limit gasoline consumption in California by 25 percent during the next decade, while expanding the market for alternative fuels as well vehicles powered by electricity and hydrogen.
